论文摘要
可以在高磁场上运行的敏感磁力计对于检测源自量子旋转小团体的磁共振信号至关重要。此类设备在量子技术中具有潜在的应用，特别是量子计算。我们提出了一种新型的实验设置，该设置使用两个DC式磁力计实施差分测量。差分测量可以在增强样品信号的同时取消背景通量信号。开发的协议使用脉冲读数，因为需要亚乳晶的温度来保持量子自旋连贯性，因此可以最大程度地减少芯片加热。也显示了概念证明实验的结果。
Sensitive magnetometers that can operate in high magnetic fields are essential for detecting magnetic resonance signals originating from small ensembles of quantum spins. Such devices have potential applications in quantum technologies, in particular quantum computing. We present a novel experimental setup implementing a differential flux measurement using two DC-SQUID magnetometers. The differential measurement allows for cancellation of background flux signals while enhancing sample signal. The developed protocol uses pulsed readout which minimizes on-chip heating since sub-Kelvin temperatures are needed to preserve quantum spin coherence. Results of a proof of concept experiment are shown as well.
